A male grabs the female around her chest with his front legs and clings until she lays her eggs in the water. ... In 2 to 3 weeks the eggs hatch into tadpoles. It can take 3 to 4 months for the tadpoles to absorb their tails, grow legs and develop lungs.
Fluid, rolling, air resistance, and not sure about the last one.
Carbohydrates is the answer
<span>If it loses that 1 electron (0 electrons, 1 proton, 1 neutron) it become an ion that is positively charge because it has more protons than electrons. [Ignore the neutrons] </span>
<span>If it gains an electron (2 electrons, 1 proton, 1 neutron) it becomes an ion that is negatively charge because it has more electrons than protons </span>
<span>A molecule - when 2 or more "different" elements combine or when 2 or more of the "same" elements combine </span>
<span>1 proton 1 electron <----- that is considered to be neutral </span>
<span>3 protons, 3 electrons <----- neutral </span>
<span>5 protons 5 electrons <----- neutral </span>
<span>6 protons, 5 electrons <-- positive ion [more protons than electrons] </span>
<span>5 protons, 8 electrons <--- negative ion [more electrons than protons] </span>
